  • Patent number: 6092787
    Abstract: An improved, safe operating, motorcycle lift having protective mechanisms to prevent the accidental release that may cause damage or injury when operating the apparatus. The present invention lifts the motorcycle through the tires of the bike, thereby preventing damage to the undercarriage or exhaust systems. The lift has a novel configuration comprised of two trestle type legs, having four telescoping extendible rods with cylindrical feet at one end. The manually operated hydraulic lift uses a connecting rod to operate synchronously the legs in unison. The legs and connecting rod comprise a novel open-based parallelogram being manually operated by a hydraulic jack. A newly designed latching mechanism prevents the accidental release, which can lower the lift. Protective curtains define the area beneath the lift by being placed around the perimeter of the work area. The 2-wheel vehicle can be clamped by either it's front wheel or by it's rear wheel.
